Global challenges and the need for a change in thinking - how is this supposed to work? This is the central question that the authors of this book illuminate from various perspectives and discuss in a critical and controversial manner. They debate current and future issues based on the major challenges of our globalized world. These include, for example, climate change, the exploitation of natural resources, the dictates of consumption, the North-South conflict, the explosion of megacities in the South, as well as the widening gap between rich and poor, and new dimensions of integration and inclusion. "Sustainability for what?" examines these and many other aspects holistically and integratively, taking into account the economic, social, and ecological pillars of sustainability, and explains them in their complexity.
